expand

问题 I am trying to expand/collapse of tableview cells in accordion cell pattern, So that, when a user taps the row they would get the detailed description of the selected row within the cell by extending the row height. I have 2 arrays, 'array' and 'detailarray' for displaying it in 'cell.textLabel.text' and 'cell.detailTextLabel.text' cells resp. now initially i have made 'cell.detailTextLabel.hidden = YES' as hidden, so that when user taps the row can get the extended text of the cell. My code,

问题 We are using Microsoft ASP.NET MVC OData WebAPI for our web services. Because of some data architecture issues surrounding hierarchy ID (which are outside the scope of this conversation), some of our GET operations have to use ODataQueryOptions and manually manipulate the expression to add additional restrictions. We do so like this (error handling code removed and calls to other methods inlined for clarity): public IQueryable<Person> Get(ODataQueryOptions<Person> oDataQueryOptions) {

问题 I have a table that kind of expands and collapses, but it's getting too messy to use it and IE and Firefox are not working properly with it. So, here's the JavaScript code: function toggle_it(itemID){ // Toggle visibility between none and '' if ((document.getElementById(itemID).style.display == 'none')) { document.getElementById(itemID).style.display = '' event.preventDefault() } else { document.getElementById(itemID).style.display = 'none'; event.preventDefault() } } And a Sample HTML:

问题 I have a (hidden) html select object in my menu attached to a menu button link, so that clicking the link shows the list so you can pick from it. When you click the button, it calls some javascript to show the <select> . Clicking away from the <select> hides the list. What I really want is to make the <select> appear fully expanded, as if you had clicked on the "down" arrow, but I can't get this working. I've tried lots of different approaches, but can't make any headway. What I'm doing

问题 I wonder how I can expand an image with height: auto for a few pixels, with pure CSS. I have got 3 responsive images in row, each in col-md-4. They have width: 100%, so height is different on each screen. The middle one image should have a bigger height than others by 20px and margined from top by -10px. I thought that this will be easy with padding on image, but actually it doesn´t work. The image doesn´t scale with padding. Function Calc() doesnt´t work on height: auto too, so I´m a bit in

问题 I need to add an header recursively to several file according to the name of the file. So I have tried: for i in *file do sed -i '1 i \A;B;C;D;E;F;G;H;${i%??}' a_${i} > header_a_${i} done the problem is that the variable reflecting the name of the file does not expand and in the header I have ${i%??} instead of part of the name file (%?? is to remove some ending characters). Any help would be great. 回答1: Use double quotes: sed '1 i\ A;B;C;D;E;F;G;H;'"${i%??}" a_${i} > header_a_${i} It doesn't

问题 I have a TreeView with several nodes and if a special node (you will see in code) is deleted, the parent node should be expanded after updating the TreeView. Here's how I tried it: public void Remove(){ ... ... else if ((NodeType)n.Tag == NodeType.Attribute) //Here I simply check if it's the "special" parent { Commands.CommandAttributeRemove cmd = (Commands.CommandAttributeRemove)mAppData.CommandFactory.Create("AttributeRemove"); cmd.Data = n.Text; cmd.ObjectClass = mObjectClass; cmd

问题 I'm making a simple dropdown menu in jQuery. And it works fine. I'm having a problem though. The problem is, that i need to keep the active page dropdown expanded In the example below the sub-menu that has the .inpath parent needs to always stay expanded. If you hover on another menu-item it should show the relevant subpages and when you hover out return to show the active subpages. Any help is greatly appriciated :-)! My html: <div id="menu"> <ul> <li><a href="">Hvem</a></li> <li><a href=""

问题 Anyone know if there is a way to create an expand all link for pages that use the semantic <details> tag? I managed to create a link that would auto-open closed details: Link to details section that expands details section as well Now I'm trying to add a link that will expand all <details> . I'm guessing you can do it with javascript but I'm weak there. Something to the effect of clicking a link that initiates a script that finds all "<details in the html and inserting the word "open" before
